The laptop does not see wifi networks 5 ghz

Support Network
1

When the system starts, the laptop tries to connect to a 5 ghz wifi network, but it fails. After that, all 5 ghz networks simply disappear and it is possible to select only 2.4 ghz networks. I’ve probably tried everything I can, but I haven’t found a solution yet.
Everything is fine with the router, I can connect from the phone.

Welcome to Manjaro! :smiling_face_with_three_hearts:

  1. Please read the information behind this link. It will help you to post necessary information.
  1. Please press the three dots … below your post and then press the :pencil2:
  • If you give us information about your system, we can see what we’re talking about and make better suggestions.
  • You can do this by using inxi in a terminal or in console.
sudo inxi --admin --verbosity=7 --filter --no-host --width
  • Personally identifiable information such as serial numbers and MAC addresses are filtered out by this command
  • Presenting the information in this way allows everyone to be familiar with the format and quickly find the items they need without missing anything.
  1. Copy the output from inxi (including the command) and paste it into your post.
  • To make it more readable, add 3 backticks ``` on an extra line before and after the pasted text.

Have you already :mag: for your problem in the forum ? (Wisdom lies in reading :wink: )

3

Can you post ip a.

4

Please see of one of the countless topics can provide some insight

Somehow I managed to find a workaround. Downgrading the linux kernel from 6.1 to 5.15 helped me.
I’m not really sure if this is the ideal solution.

7

then redo all the previous commands again and compare the outputs of the inxi-command and all others. any difference ?

8

except for the version of the linux kernel, I did not notice any differences
